Senior Mechanical Engineer

Senior Mechanical Engineer

Develop innovative designs to challenge engineering problems for a wide variety of applications related to the development of several high‑speed aerospace ground test facilities.

The engineer will perform as a task lead on a number of projects, as an individual contributor in others, and will review and approve peer designs they oversee as needed. The Senior Mechanical Engineer will develop detailed design criteria from customer requirements and use strong engineering principles and tools to develop robust and reliable solutions from the earliest conceptual stages through detailed design.

Designs are expected to include hardware such as test fixtures, custom mechanical assemblies, pressure vessels, piping systems, weldments, etc. The Senior Mechanical Engineer will regularly coordinate with engineers from other disciplines and backgrounds to ensure proper design integration. Additionally, the engineer in this role will work closely with designers and operators to ensure designed hardware is manufacturable and maintainable. The Senior Mechanical Engineer will mentor and train junior engineers through on‑the‑job training and dedicated mentorship activities.

• Sizing and conceptual/preliminary design of high‑speed ground test facility systems (e.g., blowdown and continuous high‑speed wind tunnels, arc‑jet facilities, aeropropulsion test cells, etc.)
• Sizing and conceptual/preliminary design of industrial process air systems (e.g., high‑pressure air, vacuum, and hydraulics systems, heaters, flow control valves, etc.) to meet ground‑test facility requirements
• Detailed design of high‑speed ground test facility systems, subsystems, and components (e.g., high‑pressure piping systems, hydraulic systems, converging/diverging nozzles, test sections, test article and probe support systems, diffusers and exhaust processing, etc.)

• Develop innovative designs for custom mechanical and structural hardware.
• Perform structural, thermodynamic, thermal‑structural, and flow analyses (including aerothermal) using hand calculations or appropriate software tools to validate mechanical designs.
• Develop design documentation such as presentations, white papers, calculation packages, reports, etc.
• Own and manage projects as a technical task lead, ensuring technical rigor and compliance with requirements.
• Lead and mentor junior engineers to develop strong problem solving, critical thinking, and engineering processes.
• Perform review of design documentation from other ATS and third‑party engineers.
• Present designs and design progress for customer review and feedback.

• Professional Engineer (PE) license, current.
• Background in mechanical systems, materials, civil/structural, aerofluids and/or thermal systems.
• 10+ years of relevant experience.
• BS in engineering or related field (equivalent experience may be accepted).
• Secret DoD Clearance or the ability to obtain a Secret DoD Clearance.
• Desired experience or familiarity with ANSYS or ABAQUS, RISA, Revit, CAESAR, AFT Fathom, AFT Arrow/Fathom, MATHCAD, MATLAB/Simulink or Python, and REFPROP.
• Familiarity with CAD modelling, drawing development and GD&T.
• Experience applying engineering codes and standards such as ASME BPVC, ASME B31.3, AISC 360‑10, AWS D1.1, ASME Y14.5, etc.
